Obtaining a Building Permit


To obtain a building permit, submit your application along with 2 sets of plans on a minimum of 11 x 17 paper at City Hall. When your plans have been checked and approved, your permit will be ready to be issued. You will be contacted at that time to come pay all fees and pick up your permit. If your plans are not approved, you will be contacted promptly of what needs to be done to meet regulations. 


An owner-builder must sign the form in person.  Contractors may authorize an employee to sign building permits.  This authorization must be given in writing. Contractors must also possess a current contractor’s license and have a current City of Clearlake business license at the time of permit issuance.


For Demolition Permits, we require a plot plan to be accompanied with the permit application. The plot plan should have the building/structure that is to be demolished with the exact square footage being demolished.

Please be aware that ALL Demolition Permits require Lake County Air Quality approval prior to issuance.
